Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.00933 |
| Opus 5.5 | $0.00029 | $0.00373 |
| Sonnet 5.5 | $0.00014 | $0.00187 |
| Haiku 4.5 | $0.00007 | $0.00093 |
Grade A, and why
making-payments scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Making Payments
A broad skill for preparing and initiating Newline transfers.
For a narrower transfer-only flow, create-transfer may be sufficient.
Guardrails
- Confirm with the user before calling
create-newline-transfer. - Resolve names and emails to customer and account UIDs first.
- Verify the initiating customer is active and KYC-approved before sending funds.
- Transfers are asynchronous; initial status may be
queuedorpending.
Step 1 — Identify the Initiating Customer
If you have the UID:
get-customer uid=<customer_uid>
Otherwise search first:
list-customers (filter by first_name, last_name, email, external_uid, or pool_uid)
Record:
uid→initiating_customer_uidstatuskyc_statuspool_uids
Stop if the customer is not in a valid state to initiate payments.
Step 2 — Identify the Source Account
Inspect available synthetic accounts:
get-synthetic-accounts
If needed, drill into a known account:
get-synthetic-account uid=<source_synthetic_account_uid>
Confirm:
- the account belongs to the correct customer or pool
- the account is active
- the available balance is sufficient
- the relevant payment rail details exist for the intended use
Step 3 — Identify the Destination Account
This server creates transfers between two synthetic accounts, so you need a
destination_synthetic_account_uid.
To find one:
get-synthetic-accounts
If the destination belongs to another known customer, resolve them first:
list-customers
get-customer uid=<destination_customer_uid>
get-synthetic-accounts
If no destination synthetic account exists yet, switch to new-account-setup or
managing-users-and-accounts before proceeding.
Step 4 — Choose the Transfer Rail
Exactly one of these blocks must be supplied.
Wire
wire: {
wire_instructions
}
Use for traditional wire transfers when the user provides routing instructions.
ACH
ach: {
sec_code,
service_processing,
originator_name,
company_id,
prenote,
entry_description,
effective_entry_date,
id_number
}
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
